This invention relates'to -car roofs the all steel' riveted-up type wherein metal .roofthatare rivetedto 'the-lateral sheet supporting flanges offchanfnells'haped carlines.4 y

In order' toY repair 1,a '1 rooof rthe above type it "is necessary to'f'sliearA the' rivets that secure -a damaged sheet to adjacent. sheets'.` Since' the'fsheets* are riveted to each" other,`
